How to get good range with power talkie?

Transmission range depends on local conditions and interference. You will get more range out in an open field or across a lake than you are in a building or on a city street.
As a general rule of thumb, if there are objects in the “line-of-site” between you and the other power talkies, your range will be reduced.

What are Sub-Codes/privacy codes (CTCSS/DTCS)?

In some walkie talkie there are 38 CTCSS codes and 83 DTCS codes, which means Continuous Tone Coded Squelch System and Digital Coded Squelch. The purpose of these codes is to reduce or eliminate the interference between other users that are talking. So if you are on channel 8 Sub-Code 27, you can only talk and listen to someone that is on that same channel/sub-code.
